Solar electricity generation system and method
A solar electricity generation system is provided for generating electrical current from an improved solar system. The solar electricity generation system may include semiconductor layers, a thermoelectric component, angular configuration, and a monitoring component. A bias current may be applied to amplify the electrical power generated by the semiconductor layers. A method for generating electrical current from an improved solar system using the solar electricity generation system is also provided.
The present disclosure relates to a solar electricity generation system. More particularly, the disclosure relates to generating electrical current from an improved solar system.
BACKGROUNDAs our global climate continues to change, research and development has accelerated in clean energy technologies. Cleaner power generation is replacing older pollution-causing technologies such as those reliant on combusting fossil fuels. Newer technologies based on wind and solar power generation are increasing in prevalence, but issues such as limited efficiency still need to be solved before widescale adoption can be achieved.
To these ends, researchers have been looking for ways to improve the efficiency and cost-effectiveness of solar cells. A solar photovoltaic (PV) array can include hundreds of solar cells, each of which can contribute to converting the radiation of the sun into electricity. The average efficiency is about 15%, which means nearly 85% of the sun's radiation is not being converted into electricity. Additionally, challenges relating to cooling solar panels can further limit the efficiency of a PV array.
Challenges not yet solved by the current state of the art include the capturing of more light by an area and converting a larger portion of the captured light into electricity. Standard solar cells are not believed to be able to meet these challenges, generally being configured as PN junctions. Their function is passive in nature for liberating electrons from the atoms to cross the junction and reach the bottom N-layer, further flowing through the bottom electrode plate to generate electric current. A single cell under the current state of the art can produce only very tiny amounts of electricity. A solar module must include a substantial number of interconnected solar cells to generate a sufficient amount of energy to charge a battery or be used directly to run electrical equipment.
Various attempts have been made in an effort to provide improved solar electricity generation, such as provided in the examples identified below. However, the example attempted solutions discussed below lack the useful and novel features of the present disclosure, which will be made clearer throughout this disclosure.

U.S. Pat. No. 3,232,795 to Gillette et al. discloses solar cell arrangements for outer space vehicles and the like but fails to disclose aspects of the instant disclosure including semiconductor configuration and recovery of energy via a thermoelectric component.

Non-patent literature titled “Three-Terminal Perovskite/Silicon Tandem Solar Cells with Top and Interdigitated Rear Contacts” to Tockhorn et al. discloses research regarding multi-layered perovskite cells for solar application but fails to disclose aspects of the instant disclosure including semiconductor configuration and recovery of energy via a thermoelectric component. Non-patent literature titled “The three terminal heterojunction bipolar transistor solar cell: a novel structure for multi-junction solar cells” to Marti et al. discloses research regarding use of NPN or PNP transistor structures as building blocks for solar cells but fails to disclose aspects of the instant disclosure including novel semiconductor configurations and recovery of energy via a thermoelectric component. Additional references exist which help to establish the current state of the art relating to this disclosure, all of which that are known are disclosed in a corresponding Information Disclosure Statement accompanying the instant application.

Referring now to
Generally, a solar electricity generation system enabled by this disclosure may advantageously be provided as a multi-layer and/or multi-junction system with diffraction grating to increase the effective surface area from which photons may be received over standard photovoltaic panels in the current state of the art. Semiconductor materials may be layered in a configuration to allow the electrical benefits of a controlled amplifier circuit to pass the electrons generated in one semiconductor layer to another semiconductor layer using a bias current applied to the middle semiconductor layer.
In some configurations, higher efficiency can be realized such that may produce about double the electrical output compared to older designs with the same size of the array. For example, increased transmission of photons into the semiconductor layers may approximately be doubled for an effective area of the cell surface. Additionally, the transmission of electrons inside the semiconductor layers may be quantifiably more efficient via addition of a thermoelectric component 130 that may convert at least part of excess thermal energy into recovered electrical current. This recovered electrical current may, in turn, be applied as a bias current to control and increase the transmission of energy via an amplifier circuit.
The semiconductor layers will now be discussed in greater detail.
In one embodiment, an array of semiconductor layers may be provided to facilitate the separation of electrons from atoms included in a depletion zone and creation of holes corresponding to the separated electrons. The electrons and holes may be used to create electrical power from a photovoltaic and/or other solar electrical power generation system. Examples will be provided throughout this disclosure having three semiconductor layers. However, those having skill in the art will appreciate that additional configurations and examples may be enabled by this disclosure and the use of the three-layer examples below is not intended to limit this disclosure in any way.
The semiconductor layers may include three layers of semiconductor material configured in an arrangement of P-type materials and N-type materials. For example, the semiconductor layers may include a first semiconductor layer 112, a second semiconductor layer 114, and a third semiconductor layer 116. Depletion zones may be included between the semiconductor layers, as will be appreciated by those of skill in the art. For example, a first depletion zone 122 may be located between a first semiconductor layer and a second semiconductor layer. In another example, a second depletion zone 124 may be located between the second semiconductor layer and a third semiconductor layer.
As light is received by the semiconductor layers, photons from the light may interact with atoms in the depletion zones to separate electrons from the corresponding atom. This process may create electrons and holes. As will be appreciated by those of skill in the art, holes may represent positive charges provided by atoms that may accept electrons. Once separated, the electrons and holes may become attracted to the corresponding semiconductor layers, such as for example having P-type materials and/or N-type materials. In one example, the flow of electrons in a first depletion zone 122 may flow in a first current direction and the flow of electrons in a second depletion zone 124 may flow in a second current direction. The first current direction and the second current direction may be opposite of one another, without limitation.
By including more than a single depletion zone, this disclosure advantageously provides an improvement over typical P-N junction solar cells common to the current state of the art. A system enabled by this disclosure advantageously provides an increased opportunity to use the energy from photons interacting with the depletion zones to separate holes in electrons, and thus the amount of electrical current capable of being generated may be increased.
The semiconductor layers may be constructed using a variety of semiconductor materials. As will be appreciated by those of skill in the art, a semiconductor is a material that selectively conducts electricity respective to a condition present for that semiconductor material. Semiconductors may arrange materials used in solar panels in monocrystalline, polycrystalline, and/or other organizational structures.
Monocrystalline semiconductor materials may be constructed using semiconductor cells in a homogeneous arrangement and/or orientation. Additionally, semiconductor materials may be included in polycrystalline configurations, which may include semiconductor segments in varying orientations operatively connected to one another. As will be appreciated by those of skill in the art, monocrystalline solar panels may provide an increased efficiency over their polycrystalline solar panel alternatives, but such increased efficiency may come at the expense of increased manufacturing cost.
Another type of solar panel cells that may be used with a system enabled by this disclosure include amorphous solar panels, which may differ from monocrystalline and polycrystalline semiconductor configurations by applying a semiconductor material over a thin, flexible layer that may be deformed and/or molded to a desired application.
As will be appreciated by those of skill in the art, a variety of semiconductor materials may be selected for the manufacture and installation of semiconductor layers for a system enabled by this disclosure. Illustrative materials may include semiconductors formed from crystalline inorganic solids, such as silicon, gallium arsenide, germanium, silicon carbide, gallium nitride, gallium phosphate, cadmium sulfide, lead sulfide, and/or other semiconductor materials that would be apparent to a person of skill in the art after having the benefit of this disclosure.
The semiconductor materials may be at least partially doped to provide positive and/or negative charge characteristics. For example, a semiconductor material may be doped to be used as the semiconductor layers having P-type materials, N-type materials, and other configurations that would be appreciated by those of skill in the art after having the benefit of this disclosure.
Multiple semiconductor layers may be arranged in an alternating pattern of P-type and N-type materials. For example, three semiconductor layers may be arranged in a PNP configuration, as will be appreciated by those of skill in the art. However, skilled artisans will appreciate additional applications in which NPN configurations may be used, without limitation. Examples given throughout this disclosure as PNP configurations are not intended to limit the scope of this invention except as were expressly stated otherwise.
In one embodiment, the first semiconductor layer 112 may be constructed using P-type materials, which may advantageously attract holes from the depletion layer upon interaction from a photon modifying atoms into their constituent holes and electrons. The second semiconductor layer 114 may include an N-type material, which may attract one or more electrons upon the interactions from the photon modifying atoms into the constituent holes and electrons. A third semiconductor layer 116 may be provided using P-type materials, which may similarly attract holes such as described above with the first semiconductor layer 112.
In one embodiment, the first semiconductor layer 112 may be oriented at the top of a solar electricity generation system such as one enabled by this disclosure, such that it may receive the most direct sunlight during operation. In this embodiment, the second semiconductor layer 114 may be positioned in the middle orientation, with the third semiconductor layer 116 being positioned near the bottom of the structure.
Additional components, such as a thermoelectric component 130, may be operatively attached to the third semiconductor layer 116 at the bottom of the system enabled by this disclosure. In an alternative configuration, the third semiconductor layer 116 may be oriented at the top such to receive the most direct sunlight, having the second semiconductor layer 114 being oriented in the middle, and the first semiconductor layer 112 being positioned at the bottom, which may interface with an additional component such as a thermoelectric component 130, without limitation.
By providing multiple depletion zones from which photons may separate holes and electrons from the atoms included within the depletion zone, the total amount of electrical current that may be generated by a solar electricity generation system enabled by this disclosure may advantageously be increased. Additionally, features may be provided to further increase the amount of electricity that may be generated by such a system.
In one embodiment, the semiconductor layers may be configured in an arrangement such as to provide the functionality of a transistor. For example, the semiconductor layers may be configured as a double junction transistor. In an arrangement as a transistor, the transistor may be configured to operate as an amplifier circuit. As will be appreciated by those of skill in the art, an amplifier circuit may increase the voltage of an electrical current passing through the circuit as affected by a bias current applied to the base of the transistor operating as the amplifier.
For example, the first semiconductor layer 112 may be provided as an emitter 142 of an amplifier circuit, the second semiconductor layer 114 may be provided as a base 144 of an amplifier circuit, and a third semiconductor layer 116 may be provided as a collector 146 of an amplifier circuit. The properties of electrical current flowing from the emitter 142 to the collector 146 of such an amplifier circuit may be affected by a bias current 148 applied to the base 144 of the amplifier circuit. Those having skill in the art will appreciate alternative configurations for amplifier circuits using PNP and/or NPN configurations, as will be appreciated after having the benefit of this disclosure.
The thermoelectric component will now be discussed in greater detail.
Thermal energy may be provided to the thermoelectric component 130 via operation of the semiconductor layers operatively connected to the thermoelectric component 130. For example, generation of electrical power may create heat from resistances inherent to the structure of the semiconductor layers, solar panels, and other electronics and components that may affect the operational characteristics of a system enabled by this disclosure. Additionally, as infrared energy from the sun is received by solar panels and the corresponding semiconductor layers provided by the solar panels, such infrared energy may be converted into heat.
In solar systems known in the current state of the art, such heat is considered waste and must be dissipated using heat sinks, liquid cooling, and other complex cooling systems. By including a thermoelectric component 130 operatively attached to the semiconductor layers, at least part of this heat may be converted into recovered electrical current 132, which may be output with the electrical power generated by the semiconductor layers and/or otherwise used to increase the efficiency of a system enabled by this disclosure.
In one embodiment, the recovered electrical current 132 created by the thermoelectric component 130 may be delivered to the second semiconductor layer 114 to affect the characteristics of an amplifier circuit. For example, at least part of the recovered electrical current 132 may be applied as a bias current 148 to the second semiconductor layer 114 operating as the base 144 of a transistor. This bias current 148 may drive the amplifier characteristics of the transistor in the amplifier circuit, as may be provided by the alternating semiconductor layers included by a solar power generation system enabled by this disclosure.
The angular configuration will now be discussed in greater detail.
An example will now be discussed for a semiconductor layer having two angular-oriented positions without limitation. Those of skill in the art will appreciate that additional embodiments are intended to be included within the scope and spirit of this disclosure that may include additional angular-oriented positions, which may provide further benefits to the amount of solar energy that may be captured during operation of a system enabled by this disclosure.
In an example in which two angular-oriented positions are provided for configuration of the semiconductor layers, at least part of the surface area of the semiconductor layers may be oriented such to provide an increased surface area from which light may be received. This increased collective surface may thus increase a number of photons that may be used to create electrons and holes in the depletion zones, which may thus increase the efficiency of electrical power generation.
By including multiple angular positions, a system enabled by the disclosure may advantageously increase the likelihood that the solar panels are positioned to receive light most directly from a source such as the sun. Additionally, by including multiple angular positions, at least part of the light that would normally be reflected away from the surface of a solar panel may instead be reflected to another surface of a solar panel having a different angular orientation. The reflected light may then be captured by the second solar panel section to contribute to electrical power generation, thereby further increasing the efficiency of a solar electric power generation system such as one enabled by this disclosure.
In one example including two angular orientations for the semiconductor layers, provided without limitation, a first angular-oriented position 160 may be provided to receive photons from a first light angle of incidence 156. Additionally, a second angular-oriented position 162 may be provided to receive photons from a second light angle of incidence 156. In this example, provided without limitation, the first angular-oriented position 160 may be angled such as to receive light 156 from the sun as rays of light from the sun may be received during a first half of a day. Additionally, the second angular-oriented 162 position may be angled such as to receive light 152 from the sun as rays of light may be received during the second half of the day. Additionally, during the middle portion of the day in which rays of light 154 may approximately shine directly upon the surface of the Earth, at least part of the light may be reflected from an angular surface of the first angular-oriented portion 160 and/or the second angular-oriented portion 162 such as may be received from the corresponding second angular-oriented portion 162 and/or first angular-oriented portion 160, respectively. In one embodiment, the semiconductor layers may alternate between the first angular-oriented positions and the second angular-oriented positions, which may create an approximately sawtooth shape, without limitation.
In one embodiment, each of the semiconductor layers may be configured to include the angular orientation. In this embodiment, the bottom semiconductor layer may be operatively connected to the thermoelectric component 130. For example, the thermoelectric component 130 may be shaped such as to receive the angular configuration of the semiconductor layers. In another example, an interface layer may be provided to allow transmission of thermal energy from the bottom layer of the semiconductor layers to the thermoelectric component 130, without limitation.
The monitoring component will now be discussed in greater detail. In one embodiment, a monitoring component may be provided to monitor operation of a system enabled by this disclosure and/or control operation of the system. An illustrative monitoring system may include an operational sensor to detect a condition relating to operation of the solar electricity generation system. An illustrative monitoring system may additionally include a geolocation sensor to approximate an installation location. A communication module may be included to communicate data between the monitoring component and an external device. Conditions may be remotely monitored via the monitoring component.
In one embodiment, the operational sensors may assist with detecting the conditions relating to operation of a solar electricity generation system such as when enabled by this disclosure. For example, the operational sensors may determine the power generation of such a system, detect temperatures, determine effective hours of operation, and/or detect other operational parameters that would be appreciated by a person of skill in the art after having the benefit of this disclosure.
The monitoring component may include a geolocation sensor, which may assist with determining an approximate installation location. The geolocation information may be used to approximate and/or identify a particular solar panel and associate that identification with the data and other information received from the operational sensors. Such combined information may be used to have higher resolution as to the operational parameters and conditions of such a system enabled by this disclosure.
The monitoring component may additionally include a communication module to facilitate communication of data between the monitoring component and an external device. In one example, an external device may include a server, software as a service (SaaS), smartphone, installable application, and/or other interface that would be appreciated by a person of skill in the art after having the benefit of this disclosure. In some embodiments, an operator may remotely change and control operation of a system enabled by this disclosure via the communications component and as applied by the monitoring component.

In operation, a method may be provided for generating electrical current from an improved solar system. Those of skill in the art will appreciate that the following methods are provided to illustrate an embodiment of the disclosure and should not be viewed as limiting the disclosure to only those methods or aspects. Skilled artisans will appreciate additional methods within the scope and spirit of the disclosure for performing the operations provided by the examples below after having the benefit of this disclosure. Such additional methods are intended to be included by this disclosure.
According to an embodiment of this disclosure, a method is provided for generating electricity using an improved solar electricity generation system comprising semiconductor layers to convert photons from light into electrical current. The method may include (a) generating the electrical current via a first depletion zone located between a first semiconductor layer and a second semiconductor layer that upon receiving at least part of the photons generates the electrical current in a first current direction. The method may include (b) generating the electrical current via a second depletion zone located between the second semiconductor layer and a third semiconductor layer that upon receiving at least part of the photons generates the electrical current in a second current direction. The method may include (c) generating recovered electrical current from thermal energy received from the semiconductor layers via a thermoelectric component operatively installed to the semiconductor layers.
In one embodiment, the semiconductor layers may alternate between a P-type material and an N-type material. The first semiconductor layer may include the P-type material. The second semiconductor layer may include the N-type material. The third semiconductor layer may include the P-type material. Semiconductor layers may be configured as a transistor configured as an amplifier circuit including an emitter provided by the first semiconductor layer, a base provided by the second semiconductor layer, and a collector provided by the third semiconductor layer. Upon the second semiconductor layer receiving a bias current, the electrical current flowing from the first semiconductor layer to the third semiconductor layer may be amplified.
In one embodiment, the method may further include (d) applying the recovered electrical current to the second semiconductor layer as the bias current. The semiconductor layers may be arranged to include a first angular-oriented portion to receive the photons from a first light angle of incidence and a second angular-oriented portion to receive the photons from a second light angle of incidence.
Referring now to flowchart 500 of
Electrons may be liberated by interactions with the photons in the depletion zone between the first semiconductor layer in the second semiconductor layer. (Block 522). Liberated electrons may migrate from the first depletion zone to the second semiconductor layer, which may include N-type material. (Block 524). As will be discussed below, the second semiconductor layer may receive a base voltage to affect the behavior of the semiconductor layers. Additional photons may interact with atoms in the second depletion zone located between the second semiconductor layer and the third semiconductor layer. The third semiconductor layer may be a P-type layer and may collect an increased flow of electrons and supply such electrons to an output terminal. (Block 526).
The electron supplied to the output terminal may be used to power a load, charge a battery, operate equipment, or otherwise be used as will be appreciated by a person of skill in the art after having the benefit of this disclosure. (Block 540). After the electrons are used and/or stored, electrons may follow a return path to the first semiconductor layer, which may be constructed using a P-type material, as depicted by Block 520.
Heat generated in the photovoltaic process may be radiated from the first semiconductor layer, second semiconductor layer, third semiconductor layer, and/or other aspects of the semiconductor layers to the thermoelectric component located below the final semiconductor layer. (Block 530). The thermoelectric component may then convert at least part of the thermal energy into electrical energy, for example, a DC voltage. (Block 532). The electrical energy may then be supplied to the second semiconductor layer as a bias current, which may be an N-type layer, to boost the flow of electrons through the second semiconductor layer as may be provided by an amplifier circuit. (Block 534). This process may continue as long as solar energy continues to be provided to the semiconductor layers.
